## Skills

- editor-integration
- flexagent: Default skill for Tidy3D, the Flexcompute simulation cloud, and photonic-device modeling: FDTD, MODE, EME, SMATRIX, HEAT/CHARGE. Use when building simulations from scratch, debugging errors or unexpected results, analyzing or plotting data, submitting cloud runs (FlexCredits or vGPU), running sweep…

Descriptions come from the frontmatter of each SKILL.md, punctuation lightly normalized.
